1928

First wind tunnel was designed and built

B. Melvill Jones, the first professor
of Aeronautical Engineering at Cambridge completed a small wind
tunnel in a wooden hangar used by the University Air Squadron, where
he carried out a series of aerodynamic experiments on wing stall,
streamlining and drag reduction.

As a result he presented the definitive paper on streamlining of
aircraft in 1929, which shocked the designers of the day.

The picture to the right show a comparison between the S.E.5 of
World War I and the Spitfire of World War II.
